INK-FOUNTAIN FOR PRINTING-PRESSES.

Specification of Letters Patent.

Patented Oct. 5, 1915.

Application filed October 6, 1913. Serial No. 793,502.

To all whom it may concern:

Be it known that 1, WILLIAM P. DELANEY, a citizen of theUnited States, residing at Amsterdam, county of Montgomery, and State of New York, have invented certain new and useful Improvements in InkFountains for Printing-Presses, ofwhich the following is a specification.

The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, which form a part of this specification. Similar characters refer to similar parts in the several figures therein,

'Figure l of the drawings is a top plan view vof my improved ink-fountain. Fig. 2 is a vertical section of the same taken on the broken line 2-2, in Fig.1,t'hrough the axis of the ink-feeding roller. Fig. 3 is a view in side elevation of the same. Fig.4 is a vertical cross-section of the same taken on the broken line 4'4 in Fig. 1. a

Certain objects of the invention are to automatically supply ink to the inkfeeding apparatus directly from the original package or can; to avoid waste in the feeding of ink to a printing-press; to accurately regulate from time to time the amount of ink which the ink-feeding roller is permitted to carry from the fountain; to prevent accumulation of the ink upon the ink-feeding roller, and to facilitate cleansing the inkrfeeding apparatus.

invention is shown in its prefered form, 1,,

represents an ink-feeding-roller such as is commonly employed in ink-fountains for feeding the ink from the fountain "to the type-inking surfaces, which are not shown in the drawing- This feed-roller, 1, isrotatively mounted in hearings in the yokeframe, 2, and is adapted to be rotated step by step by means of a ratchet-wheel, 3, in the usual manner. I

The ink is supplied tothe feed-roller, 1, from a reservoir, 4, and a saddle-plate, 5, which plate is. of segmental formadapted to receive and closely lit the upper half of the feed-roller, as shown in 4. The reservoir,"4, is in the form of a tube, the lower aperture the ink passes down to the surface of the feed-roll. The tubular reservoir, 4, is preferably made separable from the saddle-plate, 5, by means of a screw-connect1on at 7. The upper end of the reservoirtube, 4, has a similar separable SCl8W-COI1- nection at, 8, with a centrally-apertured plunger, 9, which is adapted to fit closely within the body of an inverted cam, 10, such as is ordinarily used as a container for printers ink. In the use of the apparatus, such a can of ink is inverted upon the plunger, 9, and its contents pass down through the central-opening, 11, in the plunger, and the reservoir, 4, and the aperture, 6, in the saddle-plate to the surface of the feed-roll. The can, 10, may be pressed down upon the plunger from time to time by hand 'or by any superimposed weight or pressure.

When the last of the contents of the can has passed down into the reservoir, 4, the empty can is removed and replaced by a full can.

By making the reservoir, 4, readily separable at its opposite ends from the saddleplate, 5, and the plunger, 9, when it is desired to use only a small quantity of ink the plunger and reservoir can be detached from the saddle-plate, 5, and the inverted plunger forced down into an upright can of ink until the ink is forced upinto the reservoir, 4, to the desired degree, whereupon the reservoir, 4, can be detached from the plunger, 9, and replaced upon the saddle-plate, 5, leaving the plunger, 9, within the can, 10.

The saddle-plate, 5, is supported in adjustable relation to the feed-roll, 1, by means of screw-threaded studs, 12, which project upward from the saddleplate through open slots, 13, in a plate, 14, mounted by means of bolts, 15, upon brackets, 16, which eXtend upward from the yoke-frame, 2,-the threaded portion of each of said studs, 11, having thereon a nut, 17, below the plate, 14, and a nut, 18, above said plate, 14. By proper adjustment of said nuts the saddle- 7 plate, 5, can be adjustably raised or lowered and then secured in the adjusted postion by tightly clamping the plate, 14, between the nuts, 17 and '18.

When the saddle-plate, 5, is in its lowermost position, it practically rests upon and substantially fits the surface of the feedroll, so that when the feed-roll is rotated in the direction of the arrow, 19, as in use, it will carry or feed out from the fountain a thin film of ink of a width substantially the same as the diameter of the aperture, 6. An upward movement of adjustment of the saddle-plate, 5, will cause its edge, past which the ink is carried by the feed-roll, to move slightly upward in a vertical plane tangential to the side of the feed-roll, causing a very gradual increase in the distance of'separation of said edge from the surface of the feed-roll, so that a considerable upward movement of adjustment of the saddleplate can be made with but slight increase in the thickness of the film of ink which is carried past said edge of the saddle-plate. Upward movement of adjustment of the saddle-plate, however, causes its surface, which is adjacent to the top of the feed-roll, to move directly upward away from the surface of the feed-roll, permitting the ink to flow lengthwise of the roll into the space thus opened up to increase the width of the film which is fed from the fountain by the feed-roll. By proper adjustment of the saddle-plate, 5, it is thus possible to accurately regulate the quantity of ink which is supplied by the feed-roll to the type-inking surfaces.

In order to prevent the ink from accumulating on the feed-roll, I have shown that part of the saddle-plate, 5, past which the surface of the feed-roll moves toward the reservoir, 4, provided with a groove, 21, leading to the aperture, 6, so that any ink remaining upon the feed-roll will not be scraped off therefrom, but will be guided back to the aperture 6.

In the preferred form of myinvention, the aperture, 6, in the saddle-plate is located at one side of the vertical plane passing through the axis of the feed-roll whereby said aperture is located adjacent to the downwardly moving surface of the feedroll, as shown in Fig. at.

The saddle-plate, 5, is preferably provided with end-flanges, 20, which closely embrace the ends of the feed-roll and prevent escape ofin-k from the ends of the roll when the saddle-plate is adjusted in somewhat elevated position relatively to the roll.

What I claim as new and desire to secure by Letters Patent is- 1. In a device of the class described and in combination, an ink-feeding roll; a segmental saddle-plate substantially conforming to'the upper side of said roll and pro vided' with an aperture located substan-' tially in rear of a vertical plane passing through the axis of the roll, said saddleplate having inwardly extending end-flanges lapping and closely fitting the respective enclsof the roll; and an ink-reservoir in communication with said aperture "in said saddle-plate.
